As mentioned in Part I of this series, cloud technology has introduced a viable alternative to the practice of creating secondary sites for disaster recovery (DR), promising to save IT organizations hundreds of thousands or even millions of dollars in infrastructure and maintenance. While the cost reduction associated with replacing dedicated DR infrastructure is intuitive, the ability of cloud solutions to meet the recovery times (RTOs and RPOs) dictated by businesses is often less well understood.

Part I suggested two key considerations in recovering IT operations from a disaster are (1) regaining access to data and (2) regaining access to applications. Today’s cloud integrated storage or cloud storage gateways can push backups or live data sets to the cloud easily and securely, enabling the first element of a cloud DR solution. With this in mind, let’s examine two strategies for application recovery using cloud-based DR:

Strategy 1: Data copies in-cloud, application recovery off-cloudOne of the simpler approaches to cloud-based DR stores data copies in the cloud and allows external, off-cloud access by applications in the case of a primary site outage. With data in the cloud accessible from nearly anywhere, applications may be recovered at a secondary site if they cannot be recovered at the primary site.

The advantage of this approach is the elimination of dedicated secondary storage infrastructure for DR. The disadvantage is the requirement for a secondary site for application recovery.

An improvement to this approach involves leveraging a hosting provider as the application recovery site, where new application servers can be provisioned on-demand in case of a disaster. Using a hosted recovery site can be considerably faster than restoring and rebuilding the original application environment and more economical than maintaining a dedicated secondary site. However, recovery times may be impacted by the time it takes for the hosting provider to provision new servers.

Application recovery off-cloud versus in-cloud

Strategy 2: Data copies in-cloud, application recovery in-cloudPerhaps a more ideal approach to cloud-based DR enables both data and application recovery in the cloud without the need for a secondary site for applications or storage. Cloud compute as-a-service represents an attractive environment for recovering applications by rapidly spinning up new virtual servers.

The process of application recovery may involve activating servers and applications via a cloud provider’s catalog. Although this process is much faster than provisioning new physical hardware, it can still be time consuming, particularly when attempting to recover tens or hundreds of servers.

Alternatively, virtual machines that resided on-premise can be reinstantiated in the cloud, similar to failover of virtual machines between hypervisors. This is possible if the same hypervisor runs on-premise and in the cloud. However, while moving virtual machine (VM) images between like hypervisors is generally straightforward, many cloud providers may not offer sufficient administrative privilege in their virtual compute environments or may not be compatible with on-premise hypervisors.

To get around these limitations and incompatibilities, an emerging option involves importing on-premise VMs into the cloud via conversion scripts and tools. An important consideration is ensuring that these conversion scripts and tools operate bidirectionally, meaning they allow a way to eventually export VMs back to the on-premise environment.

The keys to success are testing and working with a partner you trustWhile there are a variety of ways to deploy DR in the cloud, there are many subtleties and details to consider. Not surprisingly, the devil is often in the details.

Keep in mind that an important aspect of any DR strategy is conducting regular testing and validation. Additionally, working with technology partners who understand the advantages and tradeoffs of DR in the cloud can be particularly helpful.

Like any major IT undertaking, DR in the cloud requires significant planning — but the payoff can be substantial if reducing disaster recovery costs and improving availability are important to your business.

DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain.
In this power panel at @...

The Internet of Things will challenge the status quo of how IT and development organizations operate. Or will it? Certainly the fog layer of IoT requires special insights about data ontology, security and transactional integrity. But the developmental challenges are the same: People, Process and Platform and how we integrate our thinking to solve complicated problems. In his session at 19th Cloud Expo, Craig Sproule, CEO of Metavine, demonstrated how to move beyond today's coding paradigm and sh...

More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be.
We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smar...

"We build IoT infrastructure products - when you have to integrate different devices, different systems and cloud you have to build an application to do that but we eliminate the need to build an application.

Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...

In addition to all the benefits, IoT is also bringing new kind of customer experience challenges - cars that unlock themselves, thermostats turning houses into saunas and baby video monitors broadcasting over the internet. This list can only increase because while IoT services should be intuitive and simple to use, the delivery ecosystem is a myriad of potential problems as IoT explodes complexity. So finding a performance issue is like finding the proverbial needle in the haystack.

The idea of comparing data in motion (at the sensor level) to data at rest (in a Big Data server warehouse) with predictive analytics in the cloud is very appealing to the industrial IoT sector. The problem Big Data vendors have, however, is access to that data in motion at the sensor location.
In his session at @ThingsExpo, Scott Allen, CMO of FreeWave, discussed how as IoT is increasingly adopted by industrial markets, there is going to be an increased demand for sensor data from the outermos...

Okay, let me get this out there: I find the term “Citizen Data Scientist” confusing. Gartner defines a “citizen data scientist as “a person who creates or generates models that leverage predictive or prescriptive analytics but whose primary job function is outside of the field of statistics and analytics.” While we teach business users to “think like a data scientist” in their ability to identify those variables and metrics that might be better predictors of performance, I do not expect that the business stakeholders are going to be able to create and generate analytic models. I do not believe...

We have been seeing a sudden rise in the deployment of Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL). It looks like the long “AI winter” is finally over. It is interesting to note that AI was mentioned by Alan Turing in a paper he wrote back in 1950 to suggest that there is possibility to build machines with true intelligence. Then in 1956, John McCarthy organized a conference at Dartmounth and coined the phrase Artificial Intelligence. Much of the next three decades did not see much activity and hence the phrase “AI Winter” was coined. Around 1997, IBM’s Deep Blu...

My daughter called with a frantic message. She was driving my car (why she was driving my car when she has her own is the subject for another time) and a warning message appeared on the car console: “Engine overheated! Stop engine and allow to cool down” (see Figure 1).
Fortunately, my daughter was nearly home, so she got the car home, shut it down and called me immediately (I was on the road somewhere…Washington DC, Philadelphia, Knoxville, Chicago, Toronto…I don’t even remember where anymore). I called my trusty mechanic (Chuck) and he was able to work my car into the schedule when I got ba...

Almost a year ago, I wrote these words, "Technology has reached the tipping point for me, it moved from a help to a hindrance." The plethora of adrenaline- and endorphin-inducing mobile apps, 24x7 news, notifications, alerts and updates, drip fed my brain and hindered my "deep work and deep thoughts." In Cal Newport's new book titled, Deep Work he posits that most knowledge workers need concentration and substantial time, dedicated and uninterrupted, to produce their best work. He argues that a lot of technologies and open office layouts today inhibit creativity, "deep work" and "deep thoughts...

Predictions can be enlightening as we round out the end of the year, and industry analysts covering the Industrial Internet of Things (IIoT) have begun forecasting what to expect in 2017. In the ever changing digital business landscape, companies need to keep a pulse on the technology and regulatory environments to have direction on where to focus their efforts. Over the past few years, IIoT has taken on the shared title of industry 4.0, as new ways of connecting businesses and consumers impact systems infrastructures and technology integrations across many, if not all. business lines.

The holiday season is nearly upon us (I’ve already heard Christmas songs being played…really?) and retailers are usually the big winners during the holiday season. However, leading retailers are already thinking beyond the current holiday season, and not just from marketing and merchandising perspectives. These leading retailers are considering how this holiday season – and the resulting wealth of customer, product and operational data – can be converted into new analytic insights that can be used to optimize key business processes, uncover new monetization opportunities and create a more comp...

I was on a high-rise construction site 34-floors above the city. I was talking to the construction crew when a fight broke out. There was an explosion and the floor collapsed. I removed the virtual reality (VR) goggles and laughed. It was so real. The VR solutions provided an incredible experience, almost like being there. As good as my experience was, it was not reality. It was a controlled pre-programmed experience - a notional idea. Today, however, VR and sensor technologies enable a notional idea to become reality – a Real-Reality.

As we enter the final week before the 19th International Cloud Expo | @ThingsExpo in Santa Clara, CA, it's time for me to reflect on six big topics that will be important during the show. Hybrid Cloud: This general-purpose term seems to provide a comfort zone for many enterprise IT managers. It sounds reassuring to be able to work with one of the major public-cloud providers like AWS or Microsoft Azure while still maintaining an on-site presence.

2016 brought about more cyberattacks than we thought possible, especially involving ransomware, and we definitely won't see that trend breaking stride in 2017. By next year, we expect every single adult in the US will know a blood relative that has had their identity stolen - the Internal Revenue Service reported that 2.7 million people had their identities stolen in 2014 and according to TransUnion, 19 people fall victim to identity theft every minute.

For large enterprise organizations, it can be next-to-impossible to identify attacks and act to mitigate them in good time. That’s one of the reasons executives often discover security breaches when an external researcher — or worse, a journalist — gets in touch to ask why hundreds of millions of logins for their company’s services are freely available on hacker forums.
The huge volume of incoming connections, the heterogeneity of services, and the desire to avoid false positives leave enterprise security teams in a difficult spot. Finding potential security breaches is like finding a tiny ne...

Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resources of one or more underlying hosts. It's not uncommon for Docker servers to run thousands of short-te...

The IoT continued its toddler-like growth and stumbles in 2016. Here are five trends to look for in 2017 as the IoT enters its adolescence and how to benefit from them.
1. Ecosystems begin to determine winners and losers
Previously these were nice in-the-future concerns; now they will really count. Filling out a whole product value proposition through partnerships has repeatedly proven its importance across B2B and enterprise software sectors. In the IoT, they will be even more critical.

There’s a funny thing about digital transformation: we are simultaneously over-hyping it and understating it. On the one hand, every tech company in the world is talking about it. It doesn’t matter how mundane the technology; every company is somehow relating their products to digital transformation.
On the other, many people are failing to grasp the import and impact of what digital transformation really means. In far too many cases, business and IT leaders are dismissing it as nothing more than a marketing ploy. The unfortunate result is that the over-hypedness of digital transformation i...

I recently recovered from ACDF surgery where they remove a herniated or degenerative disc in the neck and fuse the cervical bones above and below the disk. My body had a huge vulnerability where one good shove or fender bender could have ruptured my spinal cord. I had some items removed and added some hardware and now my risk of injury is greatly reduced.
Breaches are occurring at a record pace, botnets are consuming IoT devices and bandwidth, and the cloud is becoming a de-facto standard for many companies. Vulnerabilities are often found at the intersection of all three of these trends, so ...

Unless your company can spend a lot of money on new technology, re-engineering your environment and hiring a comprehensive cybersecurity team, you will most likely move to the cloud or seek external service partnerships. In his session at 18th Cloud Expo, Darren Guccione, CEO of Keeper Security, revealed what you need to know when it comes to encryption in the cloud.
